Here's the listing detail that can be found here on the English Heritage website. The author's opinion is that the building is early 17thC but identifies 16thC tudor arched doorways! He could be forgiven though, as the building was substantially altered c1811 into a Georgian period mansion.

Here are some points to consider in determining the age of the Manor House. A feoffment dated 1516 states that the use of the manor is transferred to Simon Digby's wife, Alice, thereafter his son Thomas. Simon Digby's first involvement with Mansfield Woodhouse is described in a land transfer to him from the Stuffyns in 1480. The building, therefore, could be late 15thC or even earlier. A feoffment dated 1512 detailing the transfer of the manor to Simon Digby, describes Ralph Stuffyn as 'late of Mansfield Woodhouse' so he may have built the original manor house and the Digby's moved in!

The Stuffyns were servants of the King as tax collectors and officers of the Royal Forests and hunting parks, who were empowered to impose heavy fines on those found guilty of poaching the King's venison or removing timber. Literally a few yards away from the Manor House, in St Edmunds church, is the Stuffyn Chantry that was founded in 1344 by Robert Stuffyn the wealthy wool merchant, who also donated 6 acres of the Woodhouse Manor to the Felley Priory, owners of the church. A chaplain was paid six silver shillings every year to to protect the souls of past, present and future Stuffyns. It is therefore a possibility that the Stuffyn's built their home close to the chantry. In the pre-reformation period, God fearing wealthy people donated huge amounts of their own wealth to the catholic priories to prey for their souls believing that their sins would be forgiven!
